A dot is filled in on a number line to indicate that a specific value is included in the set of solutions or the interval being represented. This typically occurs when the number is part of a closed interval, such as when denoting all numbers greater than or equal to a certain value. For example, if representing the range ( x \geq 3 ), the dot at 3 would be filled in to show that 3 is included in the range. In contrast, an open circle would be used for values not included in the interval.

What is the difference between open bracket and closed bracket in limits?
( ) is a<x<b, ( ] is a<x<=b, [ ) is a<=x<b, [ ] is a<=x<=b. If there is no [ or solid bracket then there isn't a filled in dot, meaning that that number is not included. There is only a filled in dot when there is a solid bracket.
What does the open dot on a number line mean?
An open dot on a number line indicates that the point it represents is not included in the set of values being considered. This typically signifies a strict inequality, such as "<" or ">", meaning that the number at that point is excluded from the solution. For example, if the inequality is x < 3, the open dot at 3 shows that 3 itself is not part of the solutions.
